Question

Tim has suffered a vasovagal loss of consciousness, commonly known as fainting. environmental triggers, including the smell of the anatomy lab and the sight of the cadaver, caused a momentary malfunction of his autonomic nervous system (ans). how is the structural organization of the ans different from or similar to that of the somatic nervous system (sns)?

Answer 1

The structural organization of autonomic nervous system or ANS is different from somatic nervous system or SNS.

In the ANS,  the motor neurons of the central nervous system do not directly control visceral effectors. They synapse with visceral motor neurons  or  preganglionic neurons in ganglia, and the ganglionic neurons control the visceral effectors.
